See my other post where I ask about ring clamp.I got all hot and bothered about it's use and thought what the hell I'll spring for it.But given that I'd have to switch the whole rig please if if you have bought new VPI TNT 6 Arcylic platter and bearing please see my other post questions.I am sure the freindly moderator has put in next to this post most snuggly.CheersChazz
